WlNDMILL-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 779,372, dated January 3, 1905.

Application filed April 15, 1903. Serial No. 152,817-

To all whom it may concern.-

Be it known that we, THEODORE A. OVERBY and JOHN G. OVERBY, citizens of the United States, residing near Mellette, in the county of Spink and State of South Dakota, have invented a new and useful Windmill-Regulator, of which the following is a specification.

Our invention relates to that class of wind- 'mill-regulators whereby the windmill is automatically started when the water in the tank is lowered and stopped when suiiicient water has been pumped into said tank; and the objects of our improvement are, first, to provide simple and efficient means to accomplish the result referred to in a positive and reliable manner and requiring but small floats; second, to provide means to automatically stop a windmill when the well gets empty and to.

start it again when the water in the well rises to a predetermined level; third, to provide means to stop the action of the pump-rod lever when the windmill is in action; fourth, to provide means to put the dogs or pawls into engagement instantly, and thus prevent slipping and wearing; fifth, to provide means to conveniently put a windmill in or out of gear by hand and hold it so; sixth, to provide an efficient regulator without springs, and, seventh, to provide means to keep the wire of the windmill from getting tangled when a violent breeze turns the vane around and slackens the wire, &c.

We attain the objects referred to by means of the construction shown in the accompanying drawings, in which Figure 1 is 'a side view of the machine. Fig. 2 is an edge view of the support 3. Fig. 3 is a top view of the weighted lever 19. Fig. 4 is a side view of the hook 21. Fig. 5 is a top view of the weighted lever 28, to which the float is connected. Fig. 6 is a perspective view of the hook 25. Fig. 7 is a top view of the lever-dog. i Fig. 8 is a similarview of the checking-dog. Fig. 9 is a top view of the hook-weight 26. Fig. 10 is an edge View of the lifter on the pump-rod for lifting the pump-rod lever. Fig. 11 is an edge view of another pump rod lever lifter, which is clamped on the pump-rod.

Similar numbers refer to similar parts throughout the several views.

In the said drawings, 1 is the Water-tank.

2 is the pump-rod.

3 is a support fastened to the frame 4L by bolts 55. The support has thick washers 58 58, secured underneath to hold it away from the frame. 6 is the pump-rod lever pivoted to said support 3 and carrying on one end a dog 7, connected to said lever by a clamp 8, which is pivoted at both ends.

9 is a rod to limit the action of the pumprod lever.

10 is a rod fastened to the windmill-regu lating wire, passing through a hole 11 in rod 9, through hole 12 in support 3, through hole 13 in dog 7, through hole 14: in dog 15, which is fastened to the support 3 by clamp 16, which is pivoted at both ends, and then thrpugh hole 17 in support. A key or wire loop 18 is put through the said rod 10 to prevent it from slipping through the hole in support. Awire may be attached to the rod instead of the key 18 and attached to the gear-lever of the windmill, so that the windmill may be pulled out of gear independently of the regulator.

19 is a weighted lever fastened to the support by pivot 20. A hook 21 is pivoted to this lever by pivot 22. The lower end of this hook is placed between two studs 23 23. The projection 24 prevents the said hook from being pulled above the studs.

A hook 25 and a weight 26 are fastened to the weighted lever 19 by one pivot 27. The said weight 26 has a stud 58, projecting inwardly behind the hook 25, whereby the said hook 25 is held against the stud 39. Another stud, 59, keeps the weight 26 from being accidentally turned over. A weighted lever 28 is pivoted to the support by pivot 29. A wire 30 connects this lever with a bell-crank 31, which is connected with the float by a wire 33.

The lifter 34 is bolted to the pump-rod. Projecting stud 3.5 lifts the pump-rod lever. Stud 36 holds the lifter from turning out of place when bolted fast to the pump-rod. (See Fig. 10.) The lifter may be made in two pieces (see Fig. 11) and clamped to the pumprod by using a bolt on each side of the pumprod, as in case of an iron pump-rod it would not require the drilling of a hole.

The drawings show the regulator as it is when the windmill is in gear.

The operation of our regulator is as follows: When the water in the tank rises, it lifts the float 32, thus slackening wires 30 and 33, which lets weighted end 37 of lever 28 go down, which moves hook 21 off from stud 38. Thus the end of the pump-rod lever which projects toward the pump-rod drops, it being the heavier. IVeight 26 now moves hook into connection with stud 39. As the pump-rod lifts the pump-rod lever the weighted lever 19 is raised. The foot 40 of hook 21 is moved over stud 41 by weighted lever 28, which is prevented from moving too far by stud 42 on support. hen the weighted lever 19 is raised to a sufficient height, the lower end 43 of hook 25 is forced against a stud 44 on support, which moves hook 25 off from stud 39 on pump-rod lever. The said hook 25 now moves back against a stud 45. The weight 26 now rests on stud 59 of weighted lever 19. The dogs are now free to grip rod 10. The dog? has a weighted end 46, which holds it so it will grip on the downward movement only. As the pump-rod lever is raised by the pump-rod the dog 7 pulls the rod 10 downward, and it is held from going back by the dog 15, which has a weighted end 47. The continual reciprocation of the pump-rod brings the ring or head of rod 10 down on limit-rod 9, which holds the pump-rod lever up and limits the action of the regulator. The windmill is now out of gear. When the water is lowered in the tank, the float pulls on wires and 33, which pulls lever 28, which is limited in its movement this way by stud 41. The foot of hook 21 is now moved off the stud 41. The weighted lever 19 now drops. Its weighted end 49 strikes a stud 50 on dog 7, which loosens it from gripping-rod 10, and is held from gripping by the camway 51. A stud 52 strikes dog 15 and presses it down on projecting end 53 of support. When the weighted lever falls, as above stated, the hook 21 catches on stud 38 and raises the pump-rod lever out of reach of projection 35 on pump-rod. The rod 10 has now moved to its upward limit and is free to move up and down and has suflicient weight to keep a slight tension on the regulatingwire, which will prevent it from getting tangled. The windmill is now in gear and the regulator is in the position shown in drawings. If the well gets empty before sufficient water has been pumped into the tank to raise the float 32, the float in the well (not shown) pulls on wire 54, (see Fig. 1,) which is fastened to the lever 28, pulling it downwardly, thus raising the float 32 in the tank, and, as is plainly seen, the windmill will be thrown out of gear. When the water rises, it raises the float in the well, and the windmill is thrown in gear again. s

Pivoted to the bell-crank 31 is a hook 55 for the convenience of holding a windmill in or out of gear without the action of the floats. Hook said hook 55 on staple 56 to hold the windmill in gear and on staple 57 to hold the windmill out of gear.

Having thus fully described our invention, what we claim is 1. In an automatic regulator for windmills, a pump-rod lever pivoted to a support, carrying on one end a dog, a rod attached to the regulating-wire of the windmill and in engagement with said dog, also with a checkdog pivoted to said support, a weighted lever pivoted to said support and adapted to knock said dogs loose from gripping said rod attached to the regulating-wire of the windmill, a hook pivoted to said weighted lever and adapted to engage the pump-rod lever Whereby the said weighted lever is lifted, also another hook pivoted to said weighted lever, its lower arm adapted to hold the weighted lever up and its upper to engage the pumprod lever and raise it out of engagement with the projection on the pump-rod, a weighted lever 28 pivoted to said support adapted to control hook 21 by the floats connected thereto, a float in the well and wires connecting it to the weighted lever 28, substantially as set forth.
